“Take the leap! In life a lot of our biggest goals, will push us to become the best version of ourselves. Identify what is that next level for you, what excited you and makes you feel alive. Take the leap and start before you are ready. All of us are closer to the big wild dreams than we realize.” – Greg Nance

Running a marathon is hard. Imagine for a minute what it’s like to run 7 marathons, in 7 days, on 7 continents. Greg Nance recently completed this World Marathon Challenge. He started with a run of 26.2 miles / 42.2km in Antarctica, then he ran back-to-back marathons in Cape Town, Perth, Dubai, Madrid, Santiago, and Miami! The logistics behind this challenge alone are mind blowing.
